9 Claims. (Cl. 154-41) This invention relates to improvements inmachines for applying strips of material to curved surfaces, and isdirected more particularly to an improved device for covering thesurfaces of drawing rolls with parchment paper or other suitablematerials. These drawing rolls are used in spinning machines, and thekind 0f material applied totheir surfaces and the exactitude of theapplications are conducive to the production of uniformly superioryarns- Another object of the invention is the provision of a machine forapplying a denite number of layers, and/or fractions thereof, of stripmaterial to drawing rolls, thereby providing the latter with workingsurfaces having uniform A further object of the invention is theprovision in a machine for applying a definite number of layers and/orfractions thereof, of strip material to drawing rolls, and means forchanging the number of layers.

Other objects of the invention will be apparent to those skilled in theart upon the study of the following specification, in which theinvention is described in connection with a preferred embodimentthereof.

Drawing rolls (sometimes called top rolls) are used in` connection withspinning, drawing, weaving and other textile machinery. An example ofthis use is in connection with the socalled French system of drawing inwhich wool in a dry state is prepared for the spinning frame.

Over the years many materials have been tried for forming workingsurfaces on drawings, and it has been found that the most practicalmaterial for this purpose is parchment paper, which up to the presenttime is applied to the surfaces of the rolls by hand.

The applying of strips of parchment paper or any other materials to thesurfaces of drawing rollers is a tedious process as extra care must betaken to insure the uniform and` proper application. Contrasted withthis, my new and improved machine performs the operation automatically.

'I'he machine `may be set to apply a predetermined given length ofmaterial to each cylindrical portion of each roll assembly. The innerends of the material are started onto the roll members in alignment(axially) with each other, and the outer ends are finished off inalignment with each other, pneumatic means aiding in this performance.The strip materials are carried in the machine in the form of rolls, andthe strips are severed from the roll after their inner ends are startedonto the surfaces of the drawing rolls. The machine includes means forapplying a uniform coating of adhesive to the strips before they reachthe drawing rolls. The machine operates cyclically, and as soon `as onedrawing roll has the material applied thereto, it moves out, and asucceeding one is fed into position to receiveits material, etc.

The machine, therefore, applies the material rapidly and with absoluteuniformity, and the drawing rolls treated thereby impart the maximumuniformity insofar as results are concerned in drawing and spinningoperations.

Referring to the drawings, which illustrate a preferred embodiment ofthe invention:

The sprocket 93 is secured o-n theshaft 82 in any screw 94. Thefunctionlof this sprocket will'v be presently described.

The shaft 33 also has-secured thereto, at the right `end thereof asshown in Figures 4 and '7, one element, generally designated by thenumeral 91, of a Geneva movement. The member 91 has a hub 98,`a,disclike portion 99, and an actuator arm |00, the latter, of whichmay be more clearly seen in Figure 2. The actuator arm carries a roller0| pivoted on a stud |02.

A shaft |03 is journalled in the side plates 2| and 22 (Figures 5 and7), and has a portion projecting from the side plate 22 which has keyedor otherwise secured thereon the other half |04 of the Geneva movement.

The Geneva member |04 has a hub |05 which is secured to the projectingend of the shaft |03. The shape of this Geneva member may be best seenin Figure 2. It consists of a plate |04 having six equally spaced slots|06 formed therein. These slots are adapted to be engaged by the roller|0| above referred to.

`Between the slots are hollow curved'surfaces |01, each of which fit theouter surface of the disc-like portion 99. As the member 91 rotates(Figure 2), it reaches a point where the roller |0| enters the slot |06and the clearance portion 99a presents clearance for the extremities|06a and |06b of the slot |06. As the member 91 continues to rotate, theGeneva membei` |04 is rotated one-sixth of a revolution. Upon furtherrotation, the roller |0| leaves the slot |06, and the next succeedinghollow curved portion. |01 is engaged by the disc 99, so that the shaft|03 has been rotated one-sixth of a revolution and remains at rest asthe shaft 33 continues to rotate. i

Secured to the shaft |03 (Figure 3) is a disclike member |08 having ahub |09, and spaced apart therefrom on the shaft |03 is a seconddisclike member ||0 having a hub (see also Figures 8 and 5).

Referring now to Figures 6, 8 and 9, the disc |08 has a portion of itsface on the opposite side of the hub |09 stepped and terminating in thesurface ||2. A plurality of depressions 3 are formed in the disc |08 insuch a manner that they extend radially from the surface I2. There aresix such depressions, and the disc is so keyed to the shaft |03 that foreach movement of the Geneva, one depression is at the top verticalposition. (the position H36, Figure 9).

The disc I|0 has a portion of its face on the opposite side of the hubstepped and terminating in the surface II4. pressions are formed in thedisc |08 ,and eX- tend radially from the surface I|4 toward the shaft|03. There are six such depressions, and the disc is so keyed to theshaft |03 that for each movement of the Geneva, one depression is at thetop, or position II5a. These depressions formed in the discs face eachother and are adapted to accommodate the endscf the shaft |,l6 of thedrawing rolls I I1.

Continuing with Figure 8, a fiuted roller ||8 is journalled on the shaft|03 and has its left face membering up with the right face of the disc|08. A second fluted roller I9 is also journalled on the shaft |03, andhas its right face membering up with the left face of the disc ||0. Apinion |20 also journalled on the shaft |03, is riveted or otherwise Xedto the uted roller H8, and a like pinion |2| is journalled on the shaft|03 and is riveted or otherwise secured to the fluted roller A gear |22meshes with and forms a means for driving `the pinion |20 and therebyrotating the the pinion I2I, and thereby drives the fluted roller |I9.The diameter of the fluted rollers ||8 and ||9 are such that the facesor working surfaces of the drawing roll I1 are in contact therewith, andthereby prevent the ends of the shaft I I6 from resting on the bottomsof the depressions I|3a and H56. The purpose of this will hereinafter bedescribed in detail.

The gears |22 and |23, referring now to Figure 3, are keyed or otherwisesecured to a shaft |24. The shaft |24 is journalled in bearings |25 inthe side plate 2| (Figure l), and the bearing |26 in the side plate 22(Figure 2), and carries gears |22 and |23, which mesh with the pinions|20 and |2 I, respectively, in the turret. The shaft |24 also has keyedthereto a gear |21 which meshes with the gear 56 on the main driveshaft.

With the machine operating, the clutch 59, 62, is disengaged by theroller 19. When the shifter arm 68 is released, by the disengaging ofthe roller 19`by the cam 84, the spring 12 forces the clutch teeth 60,63. together to cause the gear 56 to be frictionally driven.

The gear 56 rotates the gear |21, which causes the rotation of the shaft|24, and the gears |22 and |23, which are keyed thereto, drive the:fluted rollers ||8, ||9, through the 4medium of the pinions |20 and|2|, and effect the application of the parchment paper to the surface ofthe drawing roll |1 in the operative position in the turret.

(See Figures 3, 8 and 9.)

A shaft |28 is journalled in the side plates 2| and 22, and has keyed orotherwise secured there- A plurality of deto, a sprocket |29. The shaft82 has keyed or otherwise secured thereto a sprocket 93, which was abovedescribed in connection with Figure '1. A chain |3| operatively connectsthe sprocket 93 with the sprocket |29. The shaft |28 has secured theretoa cam |32 (Figures 2, 4, 6 and 16) A shaft |33 is journalled in the sideplates 2| and 22 and has keyed or otherwise secured thereto a bell crank|34, the bell crank |34 having an arm |35 which carries a roller |36.The roller |36 is carried on a stud mounted in the arm |35 and isengaged by the surface of the cam |32 (Figure 3).

The bell crank also has an arm |31 (see Figure 2) which is connected toone end of a spring |38. The other end of the spring is connected to aloop |39 on the base 20, with the result that the spring |38 alwaysurges the roller |36 (Figure 3) in contact with the surface of the cam|32.

The shaft |33 has secured thereto a member I 40 which forms a supportfor an air pipe 4|. The .member |40 is secured to the shaft I 33, forexample by means of a set screw |42, and has its upper end, as seen inFigure 6. cross-drilled to accommodate the pipe I4|.` The cross-drilledportion may be split so as to provide a removable cap |43 and secured tothe member |42 by means of screws, one of which is shown at |44 (Figure6).

As the shaft |28 rotates (Figure 6), the roller |36 follows the conto-urof the cam |3| and thereby the air pipe |4| is caused to oscillate alonga predetermined path (defined by the contour of the cam itself). Thefunction of the air pipe 4| will hereinafter be described in connectionwith the actual application of the parchment paper to a drawing roll.

The shaft |28 has keyed or otherwise secured thereto a crank |45(Figures 1, 3 `and 5) having a radial slot |46 formed therein.

A stud shaft |41 supported in the side plate 2| has journalled thereon agear |48 and a ratchet wheel |49. The ratchet wheel is keyed orotherfluted roller ||8. A second gear |23 meshes withwiseeeiirdtttieigeail '4sf that a the "rateiiet1lJ is ririi'ri wiiifiri-turnfeirive'the gear '143.VV -"A Graine-|50 has itel'lubfjourn'a1'le'd' 'or'1 the shaft" |41 f "l A y radial-swt |I: formedA celia-r |52 fis-lpreviiiedrorreteining the 5' gea?` the=ratohetandrthe" 'hub' 'of 'the crank A| 50' l' 'f on tlefli'aftlllli jAlink'inember' |53'iec`onnectedto the-crank'slw and 50'.

The shaft 222 has aportion projecting through the side plate 22, and a crank arm 221 iskeyed thereto (see also Figure 2).

A radial slot 228 is formed in the crank 2,21. A connecting rod 229 hasits upper end, as seen in Figure 2, adjustably connected to the crank221 through the medium of a stud bearing 239 `cooperating with the slot228. This stud bearing is just like the stud bearing |54 shown in Figure18 and described above in connection with said gure.

The shaft |28 has a portion projecting through the side plate 22, towhich is keyed or otherwise through the medium of the connecting rod 229and the crank 221, the shaft 222 is oscillated and in turn the sub-frame2|9 is vertically reciprocated.

The sub-frame 2 I 9 may be termed a knife carriage, and a member 236 issecured thereto by means of a bolt 231 passing through the sub-frame 2 9and through a yoked member 238, and further engaged by a nut 239.

The member 236 has a bearing boss 249 at one end thereof and a bearingboss 24| at the other end thereof (this is better seen in Figure 6). Ashaft 242 is journalled in the bearing bosses 249 and 24| and hassecured to one end thereof a rotary knife 243 between a ange 244 formedi integral with or fixed to the shaft 242 and a washer 245, a nut 246,being provided for retaining the knife thereon.

The other end of the shaft 242 has keyed or otherwise secured thereto -agrooved pulley 241;

the belt 248 is provided for driving the pulley 261. This belt engagesthe pulley 26 on the motor 23, and also passes over idler pulleys 249and 258 (Figure 3) which are supported on stud shafts 25| and 252,respectively, carried on a bracket 255 secured to the side plate 22 bymeans of a bolt 256 extending through a slot 251 in said bracket. Theslot 251 permits the bracket to be adjusted on its support 22. Thebracket is also provided with a slot 253 along which the stud 25| may beadjusted for maintaining proper tension on the belt 248.

` It will be noted that the horizontal plane of the shaft 242 issomewhat in line with the stud shaft 25|, thereby permitting movement ofthe knife shaft without materially loosening the belt, so that the papermay be cut off at the proper time in the operative cycle of the machine.A guard 254 is provided to prevent an operator from acci- `dentallycoming in contact with the knife 243.

The knife, as may be seen from the above description, is moveddownwardly at a predetermined time during the operative cycle of themachine for cutting off the paper aftera predetermined length of paperhas passed the knife position. For causing the knife to move down at adifferent point in the machine cycle, the stud bearing 230 may beloosened and adjusted in the slot 228 to obtain a different setting, andwhen the desired setting is obtained, the stud 230 may be locked in itsadjusted position.

Between the side plate -2I and the side plate 22 are distance rods 26|,262, 263 and 264. For feeding the drawing rolls to the turret, atrackway, generally designated by the numeral 258, and including rails259 and 269 are provided (Figures 1, 2, 4 and 19).

The rails are provided with lugs 265 which engage the distance rods 26|and 262, and these lugs are provided withA screws 266 for retaining saidlugs on said distance rods (Figure 1).

1n Figure 6, the trackway is shown loaded with drawing rolls |1. Thelowest drawing roll ||1 enters the depression ||3 in the position ||3Xin the turret, so that when the turret is moved in the direction of thearrow one-sixth of a revolution, the drawing roll is carried therewithto the position H32, which has been `heretofore described as theoperative position. When this occurs, the succeeding drawing roll on thetrackway then enters the next depression ||3 in the position IISX, andin this manner the drawing rolls are successively fed into the turret.

A bar 261 is mounted on tne distance rods 263 and 264, and may besecured thereon in any suitable manner, for example by set screws one ofwhich is designated by the numeral 268. The bar 261 has secured theretoa guard rail 269 which may be seen in section in Figure 19. This guardrail has a head 21u which is substantially i triangular in cross sectionand formed integral therewith is a web portion 21| which has a verticalslot .12 formed therein to permit it to be adjusted vertically on thebar support 261.

A bolt 213 extending through the slot` 212 threadedly engages the bar261 and has a head 214 which shoulders against the web 21| for securingsaid web against the bar 261 in any adjusted position.

A cross rod 215 in the head 214 is provided to permit the operator totighten or loosen the bolt 213 by hand. The guard rail 269 prevents thedrawing rolls l1 from piling up.

A second trackway 216 is provided for leading the covered drawing rollsaway from the turret. This trackway is provided with rails similar tothe rails 259 and 260, and these rails are provided with lugs 211 whichmaybe secured to distance rods 218 and 219 by means of screws (notshown).

The upper end of the discharge trackway 216 is so positioned that as adrawing roll reaches the position ll'om, it rolls out of the depression||3 and down the trackway 216 under the urge of gravity.

A guide member 286 for the paper strip |89 has one end partiallyembracing the distance rod 264, and has its other end supported on theshaft |66 adjacent to the fiuted roller |18. vents the strip |89 fromfalling do-wn and insures its guidance between the iluted rollers |68and |19. A guide member similar to the guide rnrmber 286 is alsoprovided for the paper strip `The side plate 2| has an extension 2|a,and the side plate 22 has an extension 22a (Figures 1, 2, 3, 4 and 5). Ashaft 28| is journalled in the extensions 2 la and222t (Figures 4 and5).

Secured to the shaft 28| is a roller 282 and a second roller 283. Theserollers are exactly like the rollers |31 and |88, and they have sleeveportions 284 and 285, respectively. secured thereto by set screws 286and 281, so that the active width of the rollers may be varied inaccordance with This prelocked in any adjusted position by means of theset screws 286 and 281.`

A shaft- 288 has' end portions of reduced diameter and mounted in a slot289 in the extension 2Ia, and in a s1ot 290 in the extension 22a.

` The normal position of the air pipe is shown in dot-dash lines inFigure 6, and the solid lines in this ligure show it in its extremelowermost position.

`of delivery is constantly changed as the work progresses, through themedium of the cam |32.

Operation A number of drawing rolls ||1 are positioned on the trackway258, and they immediately roll down until the lowermost one enters thedepression |3X (Figures 6 and 9). This is, of course, assuming that themachine is empty at the beginning of the operation.

Afterthe motor 23 has been started up, the operator rotates the knob 48(Figure 7), thereby tightly clamping the hub of the wheel 43, thefriction disc 39, theV hub 31 of the sprocket 32, the friction disc 33,and the flange 4U together, thereby causing the power to be transmittedto the main shaft 33.

The roller IBI on the arm |99 engages a slot |06 of the starv wheel ofthe Geneva movement, and causes this star wheel to advance one step,which in the embodiment shown is one-sixth of a revolution (see Figure2). Now, when the shaft |03 is rotated one-sixth of a revolution, theturret (refering now to Figure 6) moves to such position that thedepressions formerly in the position ||3x and now containing the rstdrawing roll to be covered, are (together with the drawing roll) movedto the position H38, which is herein called the operative position.

By the time the first drawing roll reaches the position H39, thesucceeding depressions in the turret are in position to receive thesecond drawing roll from the trackway 258.

The paper strips |89 and |90 have passed over,

the roller 3|| and have been coated with adhesive, as indicated inFigure 6. As the action on both is the same, only one paper strip needherein be described, and the one refered to is the strip |89 whichpasses between the iluted rollers |68 and |10 (see also Figure 9). Thepaper strip is fed, diverting for a moment to Figure 1'7, through theaction of the cam |32, the linkages connected ithereto, and the pawl |63and the ratchet |49, the linkages being so set that in the presentinstance a sufficient length of paper strip is fed to go around thedrawing roller two-andone-half times. It will be understood, of course,that the linkages may be set to feed a greater drawing roll, and as thepaper continues to be fed by the ratchet feeding mechanism, this paperis wound on the drawing roll |1.

Properly timed with the mechanism is the rotary knife 243, which movesdownwardly and severs the strip |89. This severance occurs at such apoint that the cut-off piece of strip, when applied to the drawing rolland finished off, will be exactly two-and-one-half turns. Ihe severingis shown in Figure 10 in solid lines, and the 'severed end is designatedby the numeral |89a. As this end passes between the roller |91 and thedrawing roll ||1, the air pipe |4| begins to lower from the dot-dashposition shown in Figure 10, towards the solid position.

The air escaping from the cross portion 349 causes the severed end |898*to be adhered to the rest of the paper on the drawing roll without itshaving been pressed into contact with the layer of paper below by meansof the fluted roller ||8.

This leaves a short portion of the severed end |89a unadhered to therest of the roll; in other words, it is somewhat like a tab.

As the turret is again advanced, the drawing roll just covered reachesthe position IIBm, the air pipe |4| having been moved out of the wayunder control of the cam |32, whereupon the covered drawing roll, rollson to the second trackway 216.

It will be noted that as the nished drawing roll was moved from theoperative position to the discharge position |3111, the second drawingroller is at the same time moved from the position ||3x to the operativeposition |33, and the third drawing roller enters the turret at theposition |3x.

It will further be noted that the period of rotation of the flutedroller ||8 is effected by the engaged clutch teeth 60, 63, and furtherthe period of engagement is controlled by the cam 80, 84, 83, 815,acting against the roller 19 (see Figure '1). The clutch teeth aredisengaged when the drawing roll ||1 and the strip |89a being appliedthereto, reaches the position shown in dotted lines in Figure 10.

Air from the air pipe |4| forces the outer layer of the strip intoadhesive contact with the preceding layer, except for a short portionwhich is left free, as shown in Figure 1'0.

It is obvious that the cam cooperating with the roller 19 can be set forlonger or shorter periods of rotation of the iluted roller ||8. If setfor longer periods, the cam would cause the drawing roll to continue torotate in the direction of the arrow, until after the fluted roller Hi8has pressed the tab |89a into contact with the layer beneath it, thusfinishing the drawing roll off smoothly. However, for producing certainresults in the spinning of the yarn, I prefer to leave the tab |89afree.

Although I have herein shown and described a preferred embodiment of mynew and improved machine for applying parchment strips to the surfacesof drawing rolls, it is obvious that many changes may be made in thearrangement herein shown and described without departing from the spiritof the invention as set forth in the annexed claims.
